@bilalfazlani: No worries. I think Mario's answer is correct. Some advice: Please put a little more effort into your writing your posts (better title, as well as better spelling and grammar if you're able to). Too many typos or vague words makes people not want to put in the effort to answer you.

The last edit that was done to this question made it even more vague. I have to downvote for the simple the fact, the user is unable or not willing, to full explain what their question is.

If you'd like to do an upgrade, start setup from within your existing Windows installation.

If you'd like to do a fresh install (i.e. the second option), boot directly off the DVD (either change boot priority in BIOS or use some hotkey to determine the boot medium; look in your BIOS manual for reference).

The whole selection is essentially misleading, cause one option will always just tell you to do the other thing, rather than letting you pick that option.

yes i want to do upgrade. and i am running setup after starting windows. cant see that screen. does this have to do anything with my disk?

The whole process might have changed with Windows 7, so I guess it automatically does an upgrad rather than a fresh install. Otherwise (e.g. not having a valid upgrade option), it would show the selection again with the first option being greyed out. If you're unsure, just do a full disk backup (something you should do anyway before upgrading your OS), then install/upgrade.

Okay, maybe something outdated. Or it detects an incomplete previous installation? Did you cancel the installation at any time (e.g. by powering down)? Also: What version of Windows have you got so far?
